Review: Quick easy fix and enjoy the quiet again. - Working from home has its perks... one of them is being able to notice all sounds the house makes when it is relatively quiet. You can hear a toilet running over and over pretty easily. It ends up being super annoying. I did the simple changes first, the flusher and the flapper change.... that didn't do it. So got this for my Kohler toilet, fixed immediately! Perfect fit, quick install (if you're a little handy). So, if you can't figure out why your toilet keeps running, just get this part and enjoy the quiet again. Have a good day.
Review: Easily installed and worked with my kohler toilet - Don't test out the tank bolts into the gasket sleeves before installing to tank. Very difficult to pull bolts out of female sleeve. Works great with testing.

## Questions & Answers

**Q: Is the diameter of the flush valve 2"?**
A: not sure about diameter of large tube that goes between tank and bowl.  Seems larger than 2".   Cant really measure since installed. Here is link to picture https://www.plumbingsupply.com/images/kohler-flush-valve-85406.jpg   .   THis is the only one that fits Kohler Highline toilets and worth the price.  Key Is triangular gasket at bottom that only comes with Kolher

**Q: will this fit a 4609 model toilet?**
A: Yes, but if your ballcock is not adjustable style water will over flow the tube. If it is adjustable just change water level to the mark on the tube, or about 3/4 inch below the top of the tube. This item fits most all Kohler tanks with the three bolt configuration.

**Q: I installed this but still have a slow leak from tank into the bowl.  Is the flapper opening the only place water can flow from tank to bowl?**
A: make sure you have the nut tight enough or not over tigthen. Make sure the flapper is coming all the down to seal. Make sure you don't have a cracks .

**Q: Do I have to buy the fill valve too?**
A: If you're already buying the flush valve and the three bolt tank seal, you might as well replace the fill valve also. Replacing those three items will make the toilet like new for many years.
